Bis(?-di-phenyl-phosphan-yl)bis-[(tri-methyl-phosphane)cobalt(I)](Co-Co).

ABSTRACT: The title compound, [Co2{P(C6H5)2}2(C3H9P)4], was obtained by the addition of di-phenyl-phosphane to a solution of Co(CH3)(C3H9P)4. The dinuclear complex mol-ecule exhibits inversion symmetry with the inversion centre located between the two Co(I) atoms. The short Co-Co distance of 2.3670?(8)?Å lies within the range of metal-metal double bonds. As a result of inversion symmetry, the four-membered Co2P2 core is rigorously planar, and the two bridging P(C6H5)2-ligands and the terminal C3H9P ligands are arranged in a pseudo-tetra-hedral fashion about the Co(I) atom.

Crystal structure of [N,N-bis-(di-phenyl-phospho-ro-thio-yl)amidato-?2S,S']bis-(tri-phenyl-phosphane-?P)copper(I) di-chloro-methane monosolvate.

Project description:The title compound, [Cu(C24H20NP2S2)(C18H15P)2]·CH2Cl2 or [Cu(dppaS2)(PPh3)2]·CH2Cl2, is a neutral mononuclear copper(I) complex bearing an N,N-bis-(di-phenyl-phospho-rothio-yl)amidate (dppaS2-) ligand and two tri-phenyl-phosphane ligands. The molecular structure shows that the two S atoms of the dppaS2- ligand [Cu-S = 2.3462?(9) and 2.3484?(9)?Å] and the two P atoms of the two tri-phenyl-phosphane ligands [Cu-P = 2.3167?(9) and 2.2969?(9)?Å] coordinate to the copper(I) atom, resulting in a tetra-hedral coordination geometry. The crystallographically observed mol-ecular structure is compared to the results of DFT calculations.

Dichlorido[2,3,5,6-tetra-fluoro-4-(tri-fluoro-meth-yl)phenyl-?C]bis-(tri-methyl-phosphine-?P)cobalt(III).

Project description:In the title compound, [Co(C(7)F(7))Cl(2)(C(3)H(9)P)(2)], the Co(III) atom displays a trigonal-bipyramidal coordination geometry, with the two Cl ligands and the C atom of the perfluoro-tolyl ligand in the equatorial plane and the two phosphine ligands occupying axial positions. The mol-ecule has an approximate C(2v) symmetry. The trifluoro-methyl group is disordered over two positions, with nearly equal occupancies.

Chlorido-{2-[(di-methyl-amino)-meth-yl]benzene-seleno-lato-?(2) N,Se}(tri-phenyl-phosphane-?P)palladium(II).

Project description:The asymmetric unit of the title compound, [PdCl(C9H12NSe)(C18H15P)], contains two independent mol-ecules. In both cases, the Pd(2+) cations are coordinated by the Se and N atoms of the chelating bidentate 2-[(di-methyl-amino)-meth-yl]benzene-seleno-late ligand. The chloride ligand lies trans to selenium and the tri-phenyl-phosphane ligand is trans to nitro-gen. The Pd-Se bond lengths in the two independent coordination environments of Pd are 2.3801?(4) and 2.3852?(4)?Å, the Pd-P bond lengths are 2.2562?(8) and 2.2471?(8)?Å, the Pd-N bond lengths are 2.172?(2) and 2.158?(2)?Å, and the Pd-Cl bond lengths are 2.3816?(8) and 2.3801?(8)?Å. The square-planar coordination around one Pd(2+) cation is less distorted than that around the other.

Crystal structure of [1-(2,6-diiso-propyl-phen-yl)-2,4-bis-(di-methyl-amino)-5-tri-methyl-silyl-1,3,5-tri-aza-penta-dienyl-κ(2) N (1),N (5)](tri-phenyl-phosphane-κP)copper(I).

Project description:The title complex, [Cu(C21H38N5Si)(C18H15P)], was obtained from the one-pot reaction between (Dipp)N(Li)SiMe3 (Dipp = 2,6-diiso-propyl-phen-yl), Me2NCN, CuCl and PPh3. The Cu(I) atom has a distorted trigonal-planar coordination sphere. The tri-aza-penta-dienyl ligand acts as a κ(2)-donor. The N-Cu-N bond angle is 95.88 (14)°. In the tri-aza-penta-dienyl fragment, the C-N bond lengths are in the range 1.328 (5)-1.349 (5) Å, which indicates delocalization of the π-electrons in the NCNCN system.

[1,4-Bis(di-phenyl-phosphan-yl)butane-κ(2) P,P']di-bromido-palladium(II).

Project description:In the title complex, [PdBr2(C28H28P2)], the Pd(II) ion has a distorted cis-Br2P2 square-planar coordination geometry defined by two P atoms from the chelating 1,4-bis-(di-phenyl-phosphan-yl)butane ligand and two Br(-) anions. The four phenyl rings are inclined to the least-squares plane of the PdBr2P2 unit [maximum deviation = 0.1294 (7) Å], making dihedral angles of 66.3 (2), 87.2 (2), 68.8 (2) and 86.8 (2)°. The butyl-ene chain is in a gauche conformation, with a C-C-C-C torsion angle of 57.0 (8)°. Inter-molecular C-H⋯Br hydrogen bonds link the complex mol-ecules into supra-molecular layers in the ab plane. Weak π-π inter-actions, both intra- and inter-molecular [shortest inter-centroid distance = 4.598 (5) Å], are also noted in the three-dimensional architecture.

4,6-Bis(diphenyl-phosphan-yl)-2,8-di-methyl-phenoxathiin dichloro-methane monosolvate.

Project description:The title compound, C(38)H(30)OP(2)S·CH(2)Cl(2), belongs to the xanthene family of ligands containing S- and O-donor atoms in the central heterocylic ring. Positions 2 and 8 on the xanthene backbone are functionalized with methyl groups to allow for the selective functionalization of the backbone at positions 4 and 6 with diphenyl-phosphanyl units. The title compound shows a significant 'roof-like' bending along the axis of planarity involving the O- and S-donor atoms and the benzene rings, resulting in a dihedral angle between the mean planes of the benzene rings of 32.88?(13)°.

Crystal structure of dicarbon-yl[?2-methyl-enebis(di-phenyl-phosphane)-?2 P:P'][?2-2-(2,4,5-tri-methyl-phen-yl)-3-oxoprop-1-ene-1,3-di-yl](tri-phenyl-phosphane-?P)ironplatinum(Fe-Pt)-di-chloro-methane-toluene (1/1/2), [(OC)2Fe(?-dppm)(?-C(=O)C(2,4,5-C6H2Me3)=CH)Pt(PPh3)].

Project description:The title compound, [FePt(C12H12O)(C18H15P)(C25H22P2)(CO)2]·2C7H8·CH2Cl2 or [(OC)2Fe(?-dppm)(?-C(=O)C(2,4,5-C6H2Me3)=CH)Pt(PPh3)], represents an example of a diphosphane-bridged heterobimetallic dimetalla-cyclo-pentenone complex resulting from a bimetallic activation of 1-ethynyl-2,4,5-tri-methyl-benzene and a metal-coordinated carbonyl ligand. The bridging ?2-C(=O)C(2,4,5-C6H2Me3)=CH unit (stemming from a carbon-carbon coupling reaction between CO and the terminal alkyne) forms a five-membered dimetalla-cyclo-pentenone ring, in which the C=C bond is ?-coordinated to the Fe centre. The latter is connected to the Pt centre through a short metal-metal bond of 2.5770?(5)?Å. In the crystal, the complex is solvated by one di-chloro-methane and two toluene mol-ecules.

Crystal structure of di-?-iodido-bis-[(dimethyl sulfoxide-?O)(tri-phenyl-phosphane-?P)copper(I)].

Project description:The centrosymmetric dinuclear title compound, [Cu2I2(C2H6OS)2(C18H15P)2], represents the first example of a CuI complex ligated by an O-bound dimethyl sulfoxide ligand. In the crystal, the two tetrahedrally coordinated Cu(I) atoms are bridged by two ?2-iodido ligands in an almost symmetrical rhomboid geometry. The loose Cu?Cu contact of 2.9874?(8)?Å is longer than the sum of the van der Waals radii of two Cu atoms (2.8?Å), excluding a significant cupriophilic inter-action in the actual dimer. C-H?O and C-H?I hydrogen bonding interactions as well as C-H??(aryl) interactions stabilize the three-dimensional supramolecular network.
